High alumina castable is a kind of refractory castable which uses high alumina raw materials as aggregates and the powder and then be added with binding agent. High aluminum castable refractories has high mechanical strength, good thermal shock resistance, good corrosion resistance.
High alumina castable is a kind of refractory castable which uses high alumina raw materials as aggregates and the powder and then be added with binding agent. High aluminum castable refractories has high mechanical strength, good thermal shock resistance, good corrosion resistance. High temperature castable refractory is mainly used for coating, cast, furnace lining of boiler, blast furnace hot blast stove, heating furnace, ceramic kiln and various industrial furnaces.
CH Refractories manufactured high alumina refractory castable materials made from high quality raw material and with reasonable distribution of particle size according to various working condition so that can make sure good performance. There are also low cement and cement free high alumina castable refractories in our factory that can meet your various requirements.
Applications of High Alumina Castable:
High alumina dense castable also called calcium clinker, is made from industrial alumina oxide powder and selected limestone powder. Refractory castable is produced after manufactured under high temperature in rotary and grind into powder. High temperature castable refractory is for making high temperature good quality refractory castables, which is a basic furnace refractory materials used in high temperature facilities in industries like metallurgy, building material, chemical, electric plant, etc.
Advantages of CH series High Alumina Castable:
• High intensity, very competitive price
•Volume stabilityement additive
•High temperature tolerance
•Good thermal shock resistance
•Good slag resistance
